Improved electric heating crucible

The utility model relates to an improved electric heating crucible, which belongs to a melting crucible used for electric installation work; the utility model comprises a crucible and a resistance wire used for heating, wherein, a fire-proof ceramic seat on which the resistance wire is inlaid is installed in a crucible casing which is provided with a handle; the melting crucible is installed on the fire-proof ceramic seat; a melting bath of the melting crucible is divided into at least two melting baths by a partition plate. At the time of electrical installation work, the utility model can be used for heating melting soldering tins and insulating plastics simultaneously; the tinning for the soldering tin and insulating treatments can be conveniently carried out for hinged wire joints. Therefore, the utility model has the advantages of the simplification of work processes, labor saving, time saving, the uniform tinning of the wire joints and reliable weld. After the insulating plastics are uniformly wrapped on tinning joints by welding, insulating effect is good and the connection quality of the joints is high.
